I am talking about selecting different font colors form popup menus.
I will now try to better explain: I designed my gift card layout (saved as png) and uploaded it into the directory administrator/components/com_awocoupon/assets/gifcert/images
Then I opened the snowman profile and replaced the original image with mine and it worked fine. Then I needed to change the color of fonts (my card is darker so I need light colours) so I selected my favorite ones from the pop-up menus in Image Profile section. But font color didn't change at all... and remained black. color change works only with the original snowman.png image selected, not with mine.
So I made another 'experiment': I renamed my image as 'snowman.png' but also this way the color of fonts didn't change from black. So I do not understand why it works with your card image and not with mine... they are both .png.
If there is something you do not understand in my explanation or you need URL and admin access to my site just ask but please help me in fixing this.
